Right Brain vs Left Brain

So basically its a photo you are supposed to stare at, and depending on which way you see the girl spinning (clockwise vs counterclockwise) it will be determined what side of your brain you use the most. Make sense? Well anyway check the link you will see what I mean:

The photo is not a hoax either, its one of those optical illusion things that depend on your perception.

And I have no idea if the animated photo is actually related in any way to what hemisphere of your brain you use. There doesn't seem to be much explanation accompanying this short article... anyway its fun to look at.

I see her going both ways.. its sorta switches over randomly.. but I don't understand the article, and I don't know if which way you see the girl turning actually has anything to do with left/right hemisphere dominance. The article doesn't really have much explanation to it... anyway I don't know about the right brain/left brain thing. As far as I am concerned people use both sides of their brain equally.. yes certain parts are lateralized for certain functions but I don't know if there is such thing as true hemisphere dominance. I gotta look into it more.
